Description

Double-end valve blowing device and automatic valve adding machine

Technical Field

The invention relates to special equipment for manufacturing aerosol, in particular to a special conveying device for a valve body in an aerosol can.

Background

In aerosol can production, it is necessary to continuously and reliably transfer the valve to the valve-loading station. The valve of the aerosol can is generally in a thin rod shape, and a valve body is arranged at one end of the rod, so that the valve body has the requirements of positive and negative directions during transmission. When the conveying reaches the valve loading station, the accurate loading of the can mouth is also required.

In the prior art, when the problems are solved, the front and the back of the valve are processed in the conveying process, people refer to the inspiration of related equipment in the toothbrush industry, and a cylindrical valve conveying machine is adopted, so that the valve can be orderly arranged on a conveying belt in a front and back mode for conveying. However, in the operation process of the cylindrical valve feeding machine, a large number of valves in the cylinder continuously rub against each other, and the valves are easily damaged. Finally, the materials are conveyed to the tail end of the conveying belt and still need to be manually loaded into a can opening; or use a high cost robotic gripper (still prone to valve damage).

Generally speaking, the prior art has low working efficiency, and a cylinder valve feeding machine has only one output port, and has high labor intensity and low reliability.
